A HTTPS Adapter for Python Requests that sets the hostname for certificate
verification based on the Host header.
This allows requesting the IP address directly via HTTPS without getting
a "hostname doesn't match" exception.
Example usage:
>>> s.mount('https://', HostHeaderSSLAdapter())
>>> s.get("https://93.184.216.34", headers={"Host": "example.org"})
